Hello Sriram,
I think you misunderstand the [mapping] section of moses.ini (I don't
know if it's documented anywhere though, apart from the source code).
The first number specifies the decoding path, the second number is the
step index. Your configuration corresponds to this:
[mapping]
0 T 0
0 T 1
0 G 0
If you pass these parameters to train-model.perl, it should generate the
correct moses.ini:
--translation-factors 0-0+1-1 --generation-factors 1-0 --decoding-steps
t0,t1,g0
(Assuming you want the generation table from PoS to words, not the other
way around.)
Best,
Ales

Hello,
I have trained a factored model that maps source syntax to target
syntax (part of speech tags). So, the mappings that I have are,
source word -> target words (phrase table - factors 0-0)
source pos -> target pos (phrase table - factors 1-1)
target pos -> target words (generation table 0-1)
Anyone has idea of what should be order of decoding steps ? This
seemed the right order
0 T 0
0 G 1
1 T 1
but this doesn't stop processing when I give as input a sentence
tagged with part of speech tags. Any other mapping order leads to a
segmentation fault.
Any suggestions about this ? Thanks.
